The ILS system gets more power to the ground because the front tires maintain ground contact pressure. This improves field and transport ride plus increases ballasting flexibility and drastically decreases the tendency to power hop.

The mechanical system is further broken down into the mechanical drive system and mechanical suspension system.

The mechanical drive system includes:

A three-position switch is included on a MFWD clutch.

The MFWD clutch has six clutch discs and separator plates that can transfer as much as 40 percent of the tractor power through to the front ILS axle.

The front differential transfers power from the engine to the individual right and left driveshaft through a ring and pinion.

A hydraulically engaged front differential lock containing eight clutch discs and eight separator plates works in conjunction with the rear differential lock to assist the tractor in tough, wet conditions with increased power transfer to all wheels.

A right and left constant-velocity telescoping driveline provides smooth power transfer to the outboard hubs.

On 8245R, 8270R, 8295R, and 8320R Tractors, the ILS driveshaft speed is 6:1. On 8345R, 8370R, and 8400R Tractors, the ILS driveshaft ratio is 8:1. By using an 8:1 ratio on higher horsepower tractors, power can get to the wheels while minimizing the torque the U-joint experiences.

The mechanical suspension system consists of large cast, upper- and lower-control arms with cast steering knuckles for durability and reliability.

There is a high steering capacity, even with dual wheels – 25 percent increase over model year 2013

High torque in all steering positions provides maximum transfer of power to the wheels under all conditions

Fully independent suspension maintains optimum ground contact at all times

Hydraulic system

The hydraulic system consists of suspension cylinders, a control valve manifold, a front differential lock, and hydraulic accumulators.

The electrical system contains position sensors, solenoids for the control valves, and a master controller for complete automatic control of the ILS system.

How does it work?

The mechanical, hydraulic, and electrical systems work together to maintain a level and vertically-centered position of the front differential case in relation to the outboard hubs and planetaries, independent of tractor weight or dynamic loading. The system's ability to maintain a vertically centered position provides full suspension travel of 25.4 cm (10 in.). This translates to consistent soil contact for improved power to the ground as well as dampens the energy from bumps that cause a rough ride.

The tractor utilizes electronic and computer controls that monitor tractor functions and axle position. Based on those inputs, the electrical system automatically triggers hydraulic functions to raise, lower, or remain static.

The John Deere ILS uses a short/long A-arm design, which means the upper control arms are shorter than the lower control arms. During wheel movement, the upper control arm moves in a smaller arc than the lower control arm, and the difference in the two arcs creates a change in camber. The change in camber helps keep the inside and outside of the front tires perpendicular to the drive surface, a very important feature when optional front dual wheels are installed. This design provides anti-dive characteristics to naturally reduce the adverse effects of braking and acceleration.

The John Deere ILS front axle has been specifically designed to accommodate additional options, such as front 3-point hitches and front duals. To properly handle these options, large steering cylinders and knuckles provide up to twice the steering capacity of the standard MFWD beam axles so steering performance is maintained. A simple steering stop arrangement offers infinite adjustability for fine-tuning in any row spacing.

Braking system

With higher speeds and expected heavy towed implements and carts, front brakes are optional on 42-km/h (26-mph) ILS-equipped tractors and part of base equipment on 50-km/h (31-mph) ILS-equipped tractors. The braking system is applied proportionally between the front and rear axle brakes to effectively stop the tractor. There are no operator adjustments or requirements to operate the additional braking system.

With the ability to have a six-step drop from rear to front tire, the 8R equipped with an ILS axle is able to have group 49 rear tires with group 43 fronts. This allows for the benefits of group 49 tires while maintain the turning radius allowed by group 43 front tires.

NOTE: The use of group 44 tires for front duals does not allow for some row crop spacings.

A serviceability port has been added to eliminate the need to remove the front dual and hub in order to change the hub oil at the required service interval

Hitch application

In hitch applications, it is important to maintain at least 50 percent of the ballasted front-axle weight (with implement raised) for steering control. Referring to the example below, the maximum ballasted weight of the front axle is 7756 kg (17,100 lb). If the tractor has a hitch-mounted implement, when you weigh the tractor with the hitch and implement fully raised, the front weight must be at least 3878 kg (8550 lb) The front axle capacity is directly proportional to the weight that can be carried on the hitch.

The MFWD axle has a front weight carrying capacity equal to the front tire carrying capacity. For example, in row-crop applications using the popular 480/70R34 (155 load index) front tires, the highest load rating is 3878 kg (8550 lb) per tire. A total of 7756 kg (17,100 lb) at maximum tire pressure. This means (depending on tire pressure and speed) there is as much as 3878 kg (8550 lb) available for support of rear implements in transport.

Maximum load carrying capacity of the axle is determined by the load carrying capacity of the tires and whether the tractor is equipped with singles or duals.

Additional ILS features:

There is no on/off switch for ILS operation since the John Deere advanced electronic management system knows when to disengage ILS automatically. The electronic controller will activate a restricted mode of operation, when any of the following conditions are met:

Both brake pedals are pushed

The 3-point hitch raise/lower switch is activated

The tractor is placed in park

Wheel speed is less than 0.5 km/h (0.3 mph)

Tractor is correcting for an out-of-level condition

Based on the inputs received (speed, suspension displacement, braking and operator input to hitch and/or remote cylinders), the tractor determines when the system should be active or inactive, making operation simple and efficient.

MFWD CommandARM™ controls for ILS

Shortcut keys on the CommandARM enable the operator to engage or disengage MFWD on the go, even under full load without stopping or clutching. The switch can be placed in one of the following positions:

1. AUTO 2. On 3. Off (brake assist)

Mode 1 - AUTO

AUTO light

When this light-emitting diode (LED) light is lit, MFWD is on but automatically disengages when either of the following conditions are met:

As with the brake-assist position, when both brakes are depressed, the MFWD automatically engages (if not already on) to provide four-wheel braking.

Automatic MFWD angle adjustment

Mode 2 - MFWD on

MFWD light

When this LED light is lit, MFWD engages continuously.

Mode 3 MFWD off (brake assist)

When no LED lights are lit, the MFWD is off. This is also referred to as the brake-assist position. Even though the MFWD is disengaged, when both brakes are pressed at speeds above 5 km/h (3 mph), the MFWD engages to assist braking the tractor.

Differential lock

CommandARM™ controls with automatic differential lock engaged

CommandARM controls with manual differential lock engaged

The differential lock is another feature of the ILS axle. When the rear differential lock is engaged or disengaged, the front differential lock is also engaged or disengaged. This also includes a driveline shield.

If one wheel begins to slip, the differential lock can be engaged on the go and the axles are hydraulically locked together for maximum traction. There are two ways to engage the differential lock feature.

Manual differential lock - differential lock can be engaged manually using a switch on the floor or by manually depressing a button on the CommandARM console. When brakes are depressed, the differential lock will disengage

Automatic differential lock - when in auto mode, differential lock is engaged when the tractor is driving forward. Differential lock will disengage when front wheel turn angle meets disengage wheel angle setting defined by the operator via the CommandCenter or when either brake pedal is depressed. Differential lock will automatically engage when brakes are released or front wheels are turned straight.

Tire options for 8R Series Tractors

John Deere 8R Series Tractors are utilized in numerous applications that place different demands on tires. As such, multiple tire offerings are available for 8R Series Tractors to accommodate a wide range of grower needs. Tire options provide variability in terms of ground clearance, tread width, and floatation to match different operating conditions.

John Deere sources 8R Series Tractor tires from the following major brands:

Mitas® tires

Firestone® tires

Goodyear® tires

Michelin® tires

Trelleborg® tires

Tire matching (rears and fronts)

8R Series Tractor

Front and rear tires for 8R Series Tractors are sized and combined under different group sizes based on tire rolling circumference. All front tire options for 8R Series Tractors are classified as group 42, 43, or 44, while all rear tires are classified as group 47, 48, or 49. The approximate overall diameters for each group are shown in the following table.

Group

Overall diameter

42

1498 mm (59 in.)

43

1600 mm (63 in.)

44

1676 mm (66 in.)

47

1955 mm (77 in.)

48

2057 mm (81 in.)

49

2172 mm (85.5 in.)

For tractors with mechanical front-wheel drive (MFWD) or Independent-Link Suspension (ILS™) front axles, there typically needs to be five steps (or group size difference) between the front and rear tires to maintain proper tire overspeed between axles. This means the group 42 front tire needs to be matched with group 47 rear tire, and group 43 front tire needs to be matched with group 48 rear tire.

On 1500 MFWD axles, four-step combinations between front and rear tires are also acceptable (determined at the time of ordering the tractor). This means group 44 front tire can be matched with group 48 rear tire, or group 43 front tire can be matched with group 47 rear tire. Six step combinations are possible on tractors equipped with ILS, allowing group 43 front tires to be paired with group 49 rear tires in order to maintain narrower tread functionality with row crop width tire options.

Additionally, tires have a load index rating designed to report the load carrying capability of the tire.

Group 49 rear tires

John Deere 8R Series Tractors are now approved for group 49 rear tires. Group 49 tires have a larger diameter and longer footprint, which results in greater traction in most field conditions compared to smaller group size tires of the same section width and basic design. Group 49 tires also provide a larger air volume than comparable smaller group sizes, which can help control power hop in some conditions.

NOTE:

Front tread spacing for group 49 tires (group 44 fronts) has to be 1930 mm (76 in.) or wider based on tire size. For 762-mm (30-in.) tread spacings, tractors equipped with ILS may be equipped with group 49 rear tires and group 43 front tires.

710/75R42 (group 49) tires are available in singles only (see Configurator for complete offering)

480/95R50 (group 49) tires are available in duals only (see Configurator for complete offering)

Operators will experience a decrease in turning radius with group 49 tires due to the larger-diameter group 44 front tires.

Row width guidelines

Multiple tire options are available for 8R Series Tractors to accommodate multiple applications or row widths. Refer to the minimum recommended row widths for tire options based on the row-width requirements in the following table.

NOTE: Not all tires listed in the chart are available on all John Deere tractors. See your local John Deere dealer for assistance in choosing the proper tires for specific tractor models.

Hitch clearance and tread spacing

To prevent draft link interference, the distance (1) between the inside edges of the tires should be:

Category 3N hitch – 1092 mm (43 in.)

Category 3 hitch – 1168 mm (46 in.)

Category 4N hitch – 1168 mm (46 in.)

* Tires 480 mm (19 in.) and larger may not be able to reach all tread settings. Refer to the operator’s manual for detailed tread setting limitations.

45-mm (1-3/4-in.), 1000-rpm PTO

All 8R and 8RT Series Tractors come standard with a fully independent 45-mm (1-3/4-in.), 1000-rpm PTO. This 20-spline shaft is designed for high-power, heavy PTO loads that require full horsepower above 150 PTO hp.

The 8R Series Wheel Tractors offer additional mechanical and electrical speed-change PTO options to provide the versatility and flexibility needed to satisfy implement demands. An in-cab shiftable, eco version of the 45-mm (1-3/4-in.), 1000-rpm PTO is available, allowing full PTO rotations at decreased engine speeds.

Additionally, a 45-mm (1-3/4-in.), 1000-rpm PTO capable of 35 mm (1-3/8 in.), 540-rpm (6 spline)/1000-rpm (21 spline) can be ordered. To field convert to the 35-mm (1-3/8-in.) 540/1000-rpm PTO, a field kit is required (the required shaft is dependent on the hitch option).

NOTE: 540-rpm PTO options are not compatible with the Category 4 drawbar.

The PTO activation switch is located on the CommandARM™ controls. In addition, PTO engagement modulation is adjustable with settings located in the CommandCenter™ display. The PTO shaft can be slightly rotated or indexed to aid in PTO drive hookups. All PTO options feature internal lubrication with heavy-duty oil-cooled clutch plates. A PTO safety start system and seat-activated PTO warning is standard on all 8R and 8RT Series Tractors.

The following tables show when shaft kits are required for each PTO shaft based on the selected hitch option (drawbar, 3-point hitch, 80-mm ball/piton).

NOTE: Compatible with 8R Wheel Tractors. To field convert to 35-mm (1-3/8-in.), 540/1000-rpm PTO, a kit will be required. 35-mm (1-3/8-in.), 540-rpm PTO portion of this option is not compatible with the Category 4 drawbar.

Hydraulic pump options to meet varying flow requirements

A dual-pump option, featuring 85-cc and 35-cc displacement hydraulic pumps, is available for all 8R wheel models. The dual-pump system provides a hydraulic flow of 321 L/min (85 gpm), ideal for running at lower engine speeds.

Operating the tractor at reduced engine rpm contributes to a quieter cab, reduced fuel usage, and maintains the vacuum while turning and raising the planter on end rows. At 1500 erpm with a 321 L/min (85 gpm) system there will be an available flow of 229 L/min (61 gpm). This is an improvement over an available 162 L/min (43-gpm) flow when operating with a 227 L/min (60 gpm) system at 1500 erpm.

The maximum flow through one selective control valve (SCV) with a standard coupler is 132 L/min (35 gpm). A 19.1-mm (3/4-in.) high-flow coupler allows for a maximum flow rate out of one SCV of 153 L/min (40.5 gpm).

The hydraulic system is a closed-center, power-on-demand system using a load-sensing pressure-flow compensated axial piston pump with full-flow charge and flow prioritization for steering and brakes.

The pump outlet pressure available on demand can range from 3000 kPa (435 psi) for track models and 4000 kPa (580 psi) for wheel models at low standby to 20,400 kPa (2958 psi) at high standby.

The 7R, 8R, and 8RT Series Tractors feature two lighting package options:

Standard

Premium

The cab lighting pattern provides 330 degrees of coverage while the hood lighting provides the remaining 30 degrees for completely programmable 360-degree, stadium-style lighting. This ensures there are no dead zones or lighting adjustments needed. The lighting configurations are available to match various applications and ensure maximum around-the-clock productivity.

Bulb housings are large, allowing for optimum total lumens and available light. The standard lighting packages use 65-W halogen bulbs, whereas the premium lighting package uses light-emitting diode (LED) lights. In the premium lighting package, these tractors take advantage of the high-performing and efficient LED technology.

The low- and high-beam driving/work lights are adjustable. Please refer to the electrical section in the operator’s manual for complete details on adjusting lights.

Selecting a lighting mode/programmable lighting

Lighting mode selector

Operators can quickly select a lighting mode on the steering console:

Lights, off position

Road lights

Field lights

The CommandCenter™ display

The CommandCenter display allows operators to customize light settings. Operators can select only the lights they need or want for a given application and store these settings. The operator-programmed configurations can then be turned on or off with the push of a button on the CommandARM™ controls.

Programmable field lights 1

Programmable field lights 2

Beacon light

Emergency flashers

NOTE: Road/loader lights are also referred to as high-mounted driving lights for use in front hitch applications that obscure the headlights. See the Attachments section.

The battery power saver feature is also standard. When the engine is off and the outside lights have been left on, this feature is designed to avoid battery run down.

After the lights have been left on for 30 minutes and the key is in the off position, the lights cycle or blink on and off five times as an alert. The lights continue to illuminate for one more minute and then automatically shut off to protect the battery.

Field-installed options

Field-installed options are also available. To find this information, use the Build Your own Configurator application for US/Canada or Build & Price in John Deere Sales Centre for Australia/NZ.

Premium lighting

Two front corner-facing LED work lights (top of grill screen, hood mounted)

12 cab roof-mounted lights:

Four side-facing LED lights

Four corner-facing amber lights

Two rear-facing LED lights

Two adjustable front roof LED lights

Other lights:

Two rear fender-mounted LED lights

Two rear turn signal and brake lights (fender mounted)

Two folding-extremity lights

Two front belt-line LED floodlights

Rotary beacon light

The premium lighting package replaces all previous halogen and HID lights with LED lights. The only lights that are not LED are the low-beam driving lights, they remain halogen. This allows each LED light to work at a lower temperature and no one light works harder than any other. The uniformity in LED coverage allows only one type of light output surrounding the tractor.

The lighting pattern in the premium package provides industry-leading performance in nighttime visibility. LED bulbs provide maximum brightness and a true color output for excellent field definition that is easy on the operator's eyes.

The LED lights provide 40 percent greater coverage width and 10 percent more light coverage in the rear. LED lighting packages use 45 percent less amps than standard halogen lights and have an increased life expectancy over HID lights which leads to lower costs of ownership over the life of the tractor.

NOTE: Lighting packages may vary depending on region.

Programmable exit lighting

Another feature is programmable exit lighting. Exit lighting allows the lights outside the cab to stay on for up to 300 seconds. They can be programmed in increments from 0 to 300 seconds.

Refer to the operator’s manual for complete instructions on programming field, driving, and exit lighting.

John Deere’s ActiveSeat utilizes electrohydraulic technology in combination with air suspension, providing the operator with enhanced ride quality over standard air-suspension seats.

Operator movements are monitored in order to reduce vertical movement. An ActiveSeat suspension can isolate the operator from up to 90 percent of vertical movements typically seen in tractor applications.

The system uses a hydraulic cylinder that is connected to a control valve assembly. Electrohydraulic valves located in the control valve assembly automatically react to inputs from two sensors, a position sensor and an accelerometer. Inputs from these two sensors control oil flow from the tractor to the hydraulic cylinder to reduce the vertical movement of the operator.

ActiveSeat left armrest

The John Deere ActiveSeat has many of the same features of the ComfortCommand™ seat with the addition of a ride firmness switch. The ride firmness switch is located on the left-hand armrest and replaces the suspension shock-dampening seat attenuation lever on the front right-hand side of the ComfortCommand seat controls.

The ride firmness switch has three positions: plus, minus, and mid position. The three positions provide three different levels of seat performance:

The plus position provides the greatest degree of ride firmness. This position allows more of the tractor's inputs to be felt by the operator (slightly rougher ride).

The minus position provides the least degree of ride firmness, allowing minimal tractor inputs to reach the operator, resulting in maximum seat performance.

The mid position allows a balance between the plus (+) and minus (-) settings.

The ActiveSeat is also available as a heated leather seat for increased comfort and easier cleaning. For tractor applications where operating speed is not limited by the implement, the ActiveSeat can allow for faster field speeds and increased overall comfort and productivity.

CommandARM

CommandARM controls

John Deere 7R and 8R Series Tractors feature the CommandARM with integrated Generation 4 CommandCenter display. The control layout of the CommandARM utilizes a clean and efficient design which groups controls by function and builds upon John Deere’s history of intuitive and ergonomic control placement and operation. The CommandARM’s design allows for a 40 degree right seat swivel and adjustable positioning matching the operator’s preference.

Transmission controls

John Deere 7R Series Tractors with CommandQuad transmissions feature a left-hand reverser. 8R Series Tractors equipped with 16-speed PST are equipped with right-hand reverser. 7R Series Tractors equipped with e23 PST offer a left- or right-hand reverser. 7R or 8R Series Tractors equipped with AutoPowr™/IVT transmissions are offered with either a left-hand or a right-hand reverser.

The transmission control lever is placed on the CommandARM’s left side closest to the operator for convenient setting and adjustment.

Hydraulic and hitch controls

Hydraulic and hitch controls utilize fingertip paddle pots for raise/lower and extend/retract functions. An optional crossgate joystick replaces fingertip paddle pots for control of SCVs and allows for programmable hydraulic functionality according to operator preference. Rear hitch position can also be controlled with the encoder wheel located on the right side of the CommandARM. The encoder wheel allows for finite positioning of the rear 3-point hitch.

Three buttons near the encoder are for hitch set, lock, and return to height. Adjustment knobs for the 3-point hitch are located under the cover for the CommandARM’s storage compartment and allow for adjustment of the rate of drop, hitch height limit, and depth control.

ActiveCommand steering (ACS™) provides a robust and full-encompassing steering system

ACS overview

8R in transport

With ACS, John Deere has designed one of the most robust and full-encompassing steering system in the industry. Whether in the field or on the road, ACS reduces steering effort, which can result in reduced operator fatigue and can improve operator comfort.

There are four key features of the ACS system:

Dynamic road wheel offset:

A gyroscope senses tractor yaw and can automatically make small steering adjustments to provide unprecedented line-holding abilities. Drive down a bumpy road and experience how ACS makes it easier to keep the tractor straight, even over rough terrain. ACS delivers the ultimate in comfort.

ACS works to prevent over-steering when a sudden obstacle causes the operator to make a quick steering reaction.

A fail operational system

The ACS system is fail operational, which means steering is still functional in the event of any single-point failure. John Deere has gone to great lengths to help ensure the operator has the ability to steer the tractor if something goes wrong in the steering system.

For example, if the primary controller fails, a second controller takes over. If power from the alternator fails, the battery resumes control. If the engine quits running and is unable to supply hydraulic oil to the system, an electric-driven backup pump is used to supply the oil. There is a backup for ACS components.

ACS components

The ACS system consists of several key components:

Gyroscope: this is used to measure the yaw rate (turn rate) of the tractor during transport speeds.

Road-wheel angle sensors: these sensors simply measure the steer angle of the tractor.

Power supply module: this module distributes the power of the battery and alternator throughout the ACS system.

Hand-wheel angle sensors and tactile feedback unit: this includes the steering wheel position sensors and a brake which can increase or decrease resistance dependent on speed. Lighter feedback is desired during normal field use, and slightly heavier feedback is desired during transport and while the tractor is cornering at high speeds.

Controllers: two controllers are located in the back of the tractor and are the brains of the system.

Control valves: also known as steering valves, control valves are used to steer the tractor.

Electric-drive backup pump: this pump supplies oil to the steering system, brakes, and park (for towing) brake if there is no longer a sufficient oil supply to the steering and brakes.

Value of ACS

Improves line holding when driving at transport speeds

Fewer turns lock-to-lock: 3.5 turns lock-to-lock in the field for quicker headland turns and 5 turns lock-to-lock at transport speeds

The ILS system gets more power to the ground because the front tires maintain ground contact pressure. This improves field and transport ride plus increases ballasting flexibility and drastically decreases the tendency to power hop.

The mechanical system is further broken down into the mechanical drive system and mechanical suspension system.

The mechanical drive system includes:

A three-position switch is included on a MFWD clutch.

The MFWD clutch has six clutch discs and separator plates that can transfer as much as 40 percent of the tractor power through to the front ILS axle.

The front differential transfers power from the engine to the individual right and left driveshaft through a ring and pinion.

A hydraulically engaged front differential lock containing eight clutch discs and eight separator plates works in conjunction with the rear differential lock to assist the tractor in tough, wet conditions with increased power transfer to all wheels.

A right and left constant-velocity telescoping driveline provides smooth power transfer to the outboard hubs.

On 8245R, 8270R, 8295R, and 8320R Tractors, the ILS driveshaft speed is 6:1. On 8345R, 8370R, and 8400R Tractors, the ILS driveshaft ratio is 8:1. By using an 8:1 ratio on higher horsepower tractors, power can get to the wheels while minimizing the torque the U-joint experiences.

The mechanical suspension system consists of large cast, upper- and lower-control arms with cast steering knuckles for durability and reliability.

There is a high steering capacity, even with dual wheels – 25 percent increase over model year 2013

High torque in all steering positions provides maximum transfer of power to the wheels under all conditions

Fully independent suspension maintains optimum ground contact at all times

Hydraulic system

The hydraulic system consists of suspension cylinders, a control valve manifold, a front differential lock, and hydraulic accumulators.

The electrical system contains position sensors, solenoids for the control valves, and a master controller for complete automatic control of the ILS system.

How does it work?

The mechanical, hydraulic, and electrical systems work together to maintain a level and vertically-centered position of the front differential case in relation to the outboard hubs and planetaries, independent of tractor weight or dynamic loading. The system's ability to maintain a vertically centered position provides full suspension travel of 25.4 cm (10 in.). This translates to consistent soil contact for improved power to the ground as well as dampens the energy from bumps that cause a rough ride.

The tractor utilizes electronic and computer controls that monitor tractor functions and axle position. Based on those inputs, the electrical system automatically triggers hydraulic functions to raise, lower, or remain static.

The John Deere ILS uses a short/long A-arm design, which means the upper control arms are shorter than the lower control arms. During wheel movement, the upper control arm moves in a smaller arc than the lower control arm, and the difference in the two arcs creates a change in camber. The change in camber helps keep the inside and outside of the front tires perpendicular to the drive surface, a very important feature when optional front dual wheels are installed. This design provides anti-dive characteristics to naturally reduce the adverse effects of braking and acceleration.

The John Deere ILS front axle has been specifically designed to accommodate additional options, such as front 3-point hitches and front duals. To properly handle these options, large steering cylinders and knuckles provide up to twice the steering capacity of the standard MFWD beam axles so steering performance is maintained. A simple steering stop arrangement offers infinite adjustability for fine-tuning in any row spacing.

Braking system

With higher speeds and expected heavy towed implements and carts, front brakes are optional on 42-km/h (26-mph) ILS-equipped tractors and part of base equipment on 50-km/h (31-mph) ILS-equipped tractors. The braking system is applied proportionally between the front and rear axle brakes to effectively stop the tractor. There are no operator adjustments or requirements to operate the additional braking system.

With the ability to have a six-step drop from rear to front tire, the 8R equipped with an ILS axle is able to have group 49 rear tires with group 43 fronts. This allows for the benefits of group 49 tires while maintain the turning radius allowed by group 43 front tires.

NOTE: The use of group 44 tires for front duals does not allow for some row crop spacings.

A serviceability port has been added to eliminate the need to remove the front dual and hub in order to change the hub oil at the required service interval

Hitch application

In hitch applications, it is important to maintain at least 50 percent of the ballasted front-axle weight (with implement raised) for steering control. Referring to the example below, the maximum ballasted weight of the front axle is 7756 kg (17,100 lb). If the tractor has a hitch-mounted implement, when you weigh the tractor with the hitch and implement fully raised, the front weight must be at least 3878 kg (8550 lb) The front axle capacity is directly proportional to the weight that can be carried on the hitch.

The MFWD axle has a front weight carrying capacity equal to the front tire carrying capacity. For example, in row-crop applications using the popular 480/70R34 (155 load index) front tires, the highest load rating is 3878 kg (8550 lb) per tire. A total of 7756 kg (17,100 lb) at maximum tire pressure. This means (depending on tire pressure and speed) there is as much as 3878 kg (8550 lb) available for support of rear implements in transport.

Maximum load carrying capacity of the axle is determined by the load carrying capacity of the tires and whether the tractor is equipped with singles or duals.

Additional ILS features:

There is no on/off switch for ILS operation since the John Deere advanced electronic management system knows when to disengage ILS automatically. The electronic controller will activate a restricted mode of operation, when any of the following conditions are met:

Both brake pedals are pushed

The 3-point hitch raise/lower switch is activated

The tractor is placed in park

Wheel speed is less than 0.5 km/h (0.3 mph)

Tractor is correcting for an out-of-level condition

Based on the inputs received (speed, suspension displacement, braking and operator input to hitch and/or remote cylinders), the tractor determines when the system should be active or inactive, making operation simple and efficient.

MFWD CommandARM™ controls for ILS

Shortcut keys on the CommandARM enable the operator to engage or disengage MFWD on the go, even under full load without stopping or clutching. The switch can be placed in one of the following positions:

1. AUTO 2. On 3. Off (brake assist)

Mode 1 - AUTO

AUTO light

When this light-emitting diode (LED) light is lit, MFWD is on but automatically disengages when either of the following conditions are met:

As with the brake-assist position, when both brakes are depressed, the MFWD automatically engages (if not already on) to provide four-wheel braking.

Automatic MFWD angle adjustment

Mode 2 - MFWD on

MFWD light

When this LED light is lit, MFWD engages continuously.

Mode 3 MFWD off (brake assist)

When no LED lights are lit, the MFWD is off. This is also referred to as the brake-assist position. Even though the MFWD is disengaged, when both brakes are pressed at speeds above 5 km/h (3 mph), the MFWD engages to assist braking the tractor.

Differential lock

CommandARM™ controls with automatic differential lock engaged

CommandARM controls with manual differential lock engaged

The differential lock is another feature of the ILS axle. When the rear differential lock is engaged or disengaged, the front differential lock is also engaged or disengaged. This also includes a driveline shield.

If one wheel begins to slip, the differential lock can be engaged on the go and the axles are hydraulically locked together for maximum traction. There are two ways to engage the differential lock feature.

Manual differential lock - differential lock can be engaged manually using a switch on the floor or by manually depressing a button on the CommandARM console. When brakes are depressed, the differential lock will disengage

Automatic differential lock - when in auto mode, differential lock is engaged when the tractor is driving forward. Differential lock will disengage when front wheel turn angle meets disengage wheel angle setting defined by the operator via the CommandCenter or when either brake pedal is depressed. Differential lock will automatically engage when brakes are released or front wheels are turned straight.

Tire options for 8R Series Tractors

John Deere 8R Series Tractors are utilized in numerous applications that place different demands on tires. As such, multiple tire offerings are available for 8R Series Tractors to accommodate a wide range of grower needs. Tire options provide variability in terms of ground clearance, tread width, and floatation to match different operating conditions.

John Deere sources 8R Series Tractor tires from the following major brands:

Mitas® tires

Firestone® tires

Goodyear® tires

Michelin® tires

Trelleborg® tires

Tire matching (rears and fronts)

8R Series Tractor

Front and rear tires for 8R Series Tractors are sized and combined under different group sizes based on tire rolling circumference. All front tire options for 8R Series Tractors are classified as group 42, 43, or 44, while all rear tires are classified as group 47, 48, or 49. The approximate overall diameters for each group are shown in the following table.

Group

Overall diameter

42

1498 mm (59 in.)

43

1600 mm (63 in.)

44

1676 mm (66 in.)

47

1955 mm (77 in.)

48

2057 mm (81 in.)

49

2172 mm (85.5 in.)

For tractors with mechanical front-wheel drive (MFWD) or Independent-Link Suspension (ILS™) front axles, there typically needs to be five steps (or group size difference) between the front and rear tires to maintain proper tire overspeed between axles. This means the group 42 front tire needs to be matched with group 47 rear tire, and group 43 front tire needs to be matched with group 48 rear tire.

On 1500 MFWD axles, four-step combinations between front and rear tires are also acceptable (determined at the time of ordering the tractor). This means group 44 front tire can be matched with group 48 rear tire, or group 43 front tire can be matched with group 47 rear tire. Six step combinations are possible on tractors equipped with ILS, allowing group 43 front tires to be paired with group 49 rear tires in order to maintain narrower tread functionality with row crop width tire options.

Additionally, tires have a load index rating designed to report the load carrying capability of the tire.

Group 49 rear tires

John Deere 8R Series Tractors are now approved for group 49 rear tires. Group 49 tires have a larger diameter and longer footprint, which results in greater traction in most field conditions compared to smaller group size tires of the same section width and basic design. Group 49 tires also provide a larger air volume than comparable smaller group sizes, which can help control power hop in some conditions.

NOTE:

Front tread spacing for group 49 tires (group 44 fronts) has to be 1930 mm (76 in.) or wider based on tire size. For 762-mm (30-in.) tread spacings, tractors equipped with ILS may be equipped with group 49 rear tires and group 43 front tires.

710/75R42 (group 49) tires are available in singles only (see Configurator for complete offering)

480/95R50 (group 49) tires are available in duals only (see Configurator for complete offering)

Operators will experience a decrease in turning radius with group 49 tires due to the larger-diameter group 44 front tires.

Row width guidelines

Multiple tire options are available for 8R Series Tractors to accommodate multiple applications or row widths. Refer to the minimum recommended row widths for tire options based on the row-width requirements in the following table.

NOTE: Not all tires listed in the chart are available on all John Deere tractors. See your local John Deere dealer for assistance in choosing the proper tires for specific tractor models.

Hitch clearance and tread spacing

To prevent draft link interference, the distance (1) between the inside edges of the tires should be:

Category 3N hitch – 1092 mm (43 in.)

Category 3 hitch – 1168 mm (46 in.)

Category 4N hitch – 1168 mm (46 in.)

* Tires 480 mm (19 in.) and larger may not be able to reach all tread settings. Refer to the operator’s manual for detailed tread setting limitations.

Operating the tractor at reduced engine rpm contributes to a quieter cab, reduced fuel usage, and maintains the vacuum while turning and raising the planter on end rows. At 1500 erpm with a 321 L/min (85 gpm) system there will be an available flow of 229 L/min (61 gpm). This is an improvement over an available 162 L/min (43-gpm) flow when operating with a 227 L/min (60 gpm) system at 1500 erpm.

The maximum flow through one selective control valve (SCV) with a standard coupler is 132 L/min (35 gpm). A 19.1-mm (3/4-in.) high-flow coupler allows for a maximum flow rate out of one SCV of 153 L/min (40.5 gpm).

The hydraulic system is a closed-center, power-on-demand system using a load-sensing pressure-flow compensated axial piston pump with full-flow charge and flow prioritization for steering and brakes.

The pump outlet pressure available on demand can range from 3000 kPa (435 psi) for track models and 4000 kPa (580 psi) for wheel models at low standby to 20,400 kPa (2958 psi) at high standby.

The 7R, 8R, and 8RT Series Tractors feature two lighting package options:

The premium lighting package replaces all previous halogen and HID lights with LED lights. The only lights that are not LED are the low-beam driving lights, they remain halogen. This allows each LED light to work at a lower temperature and no one light works harder than any other. The uniformity in LED coverage allows only one type of light output surrounding the tractor.

The lighting pattern in the premium package provides industry-leading performance in nighttime visibility. LED bulbs provide maximum brightness and a true color output for excellent field definition that is easy on the operator's eyes.

The LED lights provide 40 percent greater coverage width and 10 percent more light coverage in the rear. LED lighting packages use 45 percent less amps than standard halogen lights and have an increased life expectancy over HID lights which leads to lower costs of ownership over the life of the tractor.

NOTE: Lighting packages may vary depending on region.

Programmable exit lighting

Another feature is programmable exit lighting. Exit lighting allows the lights outside the cab to stay on for up to 300 seconds. They can be programmed in increments from 0 to 300 seconds.

Refer to the operator’s manual for complete instructions on programming field, driving, and exit lighting.

John Deere’s ActiveSeat utilizes electrohydraulic technology in combination with air suspension, providing the operator with enhanced ride quality over standard air-suspension seats.

Operator movements are monitored in order to reduce vertical movement. An ActiveSeat suspension can isolate the operator from up to 90 percent of vertical movements typically seen in tractor applications.

The system uses a hydraulic cylinder that is connected to a control valve assembly. Electrohydraulic valves located in the control valve assembly automatically react to inputs from two sensors, a position sensor and an accelerometer. Inputs from these two sensors control oil flow from the tractor to the hydraulic cylinder to reduce the vertical movement of the operator.

ActiveSeat left armrest

The John Deere ActiveSeat has many of the same features of the ComfortCommand™ seat with the addition of a ride firmness switch. The ride firmness switch is located on the left-hand armrest and replaces the suspension shock-dampening seat attenuation lever on the front right-hand side of the ComfortCommand seat controls.

The ride firmness switch has three positions: plus, minus, and mid position. The three positions provide three different levels of seat performance:

The plus position provides the greatest degree of ride firmness. This position allows more of the tractor's inputs to be felt by the operator (slightly rougher ride).

The minus position provides the least degree of ride firmness, allowing minimal tractor inputs to reach the operator, resulting in maximum seat performance.

The mid position allows a balance between the plus (+) and minus (-) settings.

The ActiveSeat is also available as a heated leather seat for increased comfort and easier cleaning. For tractor applications where operating speed is not limited by the implement, the ActiveSeat can allow for faster field speeds and increased overall comfort and productivity.

CommandARM

CommandARM controls

John Deere 7R and 8R Series Tractors feature the CommandARM with integrated Generation 4 CommandCenter display. The control layout of the CommandARM utilizes a clean and efficient design which groups controls by function and builds upon John Deere’s history of intuitive and ergonomic control placement and operation. The CommandARM’s design allows for a 40 degree right seat swivel and adjustable positioning matching the operator’s preference.

Transmission controls

John Deere 7R Series Tractors with CommandQuad transmissions feature a left-hand reverser. 8R Series Tractors equipped with 16-speed PST are equipped with right-hand reverser. 7R Series Tractors equipped with e23 PST offer a left- or right-hand reverser. 7R or 8R Series Tractors equipped with AutoPowr™/IVT transmissions are offered with either a left-hand or a right-hand reverser.

The transmission control lever is placed on the CommandARM’s left side closest to the operator for convenient setting and adjustment.

Hydraulic and hitch controls

Hydraulic and hitch controls utilize fingertip paddle pots for raise/lower and extend/retract functions. An optional crossgate joystick replaces fingertip paddle pots for control of SCVs and allows for programmable hydraulic functionality according to operator preference. Rear hitch position can also be controlled with the encoder wheel located on the right side of the CommandARM. The encoder wheel allows for finite positioning of the rear 3-point hitch.

Three buttons near the encoder are for hitch set, lock, and return to height. Adjustment knobs for the 3-point hitch are located under the cover for the CommandARM’s storage compartment and allow for adjustment of the rate of drop, hitch height limit, and depth control.

ActiveCommand steering (ACS™) provides a robust and full-encompassing steering system

ACS overview

8R in transport

With ACS, John Deere has designed one of the most robust and full-encompassing steering system in the industry. Whether in the field or on the road, ACS reduces steering effort, which can result in reduced operator fatigue and can improve operator comfort.

There are four key features of the ACS system:

Dynamic road wheel offset:

A gyroscope senses tractor yaw and can automatically make small steering adjustments to provide unprecedented line-holding abilities. Drive down a bumpy road and experience how ACS makes it easier to keep the tractor straight, even over rough terrain. ACS delivers the ultimate in comfort.

ACS works to prevent over-steering when a sudden obstacle causes the operator to make a quick steering reaction.

A fail operational system

The ACS system is fail operational, which means steering is still functional in the event of any single-point failure. John Deere has gone to great lengths to help ensure the operator has the ability to steer the tractor if something goes wrong in the steering system.

For example, if the primary controller fails, a second controller takes over. If power from the alternator fails, the battery resumes control. If the engine quits running and is unable to supply hydraulic oil to the system, an electric-driven backup pump is used to supply the oil. There is a backup for ACS components.

ACS components

The ACS system consists of several key components:

Gyroscope: this is used to measure the yaw rate (turn rate) of the tractor during transport speeds.

Road-wheel angle sensors: these sensors simply measure the steer angle of the tractor.

Power supply module: this module distributes the power of the battery and alternator throughout the ACS system.

Hand-wheel angle sensors and tactile feedback unit: this includes the steering wheel position sensors and a brake which can increase or decrease resistance dependent on speed. Lighter feedback is desired during normal field use, and slightly heavier feedback is desired during transport and while the tractor is cornering at high speeds.

Controllers: two controllers are located in the back of the tractor and are the brains of the system.

Control valves: also known as steering valves, control valves are used to steer the tractor.

Electric-drive backup pump: this pump supplies oil to the steering system, brakes, and park (for towing) brake if there is no longer a sufficient oil supply to the steering and brakes.

Value of ACS

Improves line holding when driving at transport speeds

Fewer turns lock-to-lock: 3.5 turns lock-to-lock in the field for quicker headland turns and 5 turns lock-to-lock at transport speeds
